AGRICULTURAL IMPLEMENT.

Application filed September To all 1117mm may concern:

Be it known that I, RUBIN L. DIAMOND, a citizen of the United States, residing at M-cHcnry, in the county of Stone and State of Mississippi, have invented certain new and useful Improvements in Agricultural l n'iplements, of which the following is a specification, reference being had to the accompanying drawings.

This inveiition relates to certain improvements in agricultural implements and .it is an object of the invention to provide a novel and improved device of this general charact if provided with means whereby the ground workin elements may be adjusted as the occasions of practice may prefer.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved agricultural implement whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set'fort-h.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a'view in top plan illustratin accordance with an embodiment of my invention Figure 2 is a vertical sectional view taken longitudinally through the structure as illustrated in Figure 1;

Figure 3 is an enlarged fragmentary elevational view illustrating in detail the mounting for a set of cultivating elements;

Figure 4 is a detailed sectional view taken substantially on the line 44 of Figure 3;

'Fignre 5 is a view in top plan of a set of cultivating elements unapplied;

Figure 6 -is a. view in perspective of the spacing plate associated with the cultivating elements una-pplied.

As disclosed in the accompanying drawings, F denotes a frame mounted upon the arched axle A which is provided at its forward end portion with a suitable draft rigging D. Depending from the frame F at a predetermined point in advance of the axle A and extending transversely thereof a, cross mg an agricultural implement constructed 6, 1924. Serial No. 736,341.

member or beam B. The beam B adjacent each end thereof is provided with a rearwardly directed plate 1 provided with a series of longitudinally disposed openings 2 through which is selectively engaged a bolt 3, said bolt 8 providing a pivotal connection for the intermediate or main plow beam 4. The rear end portion of the beam 4 has secured to a side thereof a rigid link 5 through which is freely disposed a vertically directed rod 6. This rod 6 is also selectively directed through an eye or guide member? extending inwardly from the rear cross member 8 of the frame F. The rod 6 overlies an arcuate member 9 carried by said rear member 8 and'is held thereto by a U-bolt 1O selectively engaged through the opening 11 whereby the beam 4 may be maintained in its desired posit-ion with respect to the longitudinal center of the implement.

interposed between the beam 4 and such eye or guide member 7 is an eXpansible member 12, herein disclosed as a. coil spring, and

' which operates to constantly urge said beam 4 downwardly yet permits the same to have upward swinging movement as desired.

As herein disclosed, the beam 4 forwardly of the link 5 has pivotally engaged therewith, as at 14, an end portion of a rod 15 the upper or opposite end portion of which being pivotally connected, as at 16, with an arm of a bell crank lever 17. The heel portion of the bell crank lever 17 is pivotally supported, as at 18, by an upstanding bracket fixed to the rear portion of the flooring 19 overlying the central portion of the frame F.

The second arm of the bell crank lever 17 has pivotally engaged therewith, as at 20, a rod 21 which is also pivotally con nected, as at 22, with an upstanding lever 23. This lever 23 is pivot-ally connected, as at 24, with the upstanding rack 25 carried by the floor 19 and carried by the lever 23 is a latch mechanism 26 of a conventional type for coaction with the rack 25.

Upon proper manipulation of the lever 23 the beam 4 may be readily raised when desired and maintained in required vertical adjustment. At opposite sides of the beam 4 and pivotally connected therewith, as at 2-7, at points spaced lengthwise of said beam 4 are the supplemental beams 28, one of said beams 28 te minating inwardly of the rear inn block or hearing: (it).

end of the beam l while the second beam 2h terminates beyond said rear end of the brain. lhe pivotal connection 27 oil the beams :29 with the beam el; permits said beams :lito be laterally adjusted one with respect to the other and with respect to the beam :l: and the l aims 28 are nniintained in such desired adjusted positions by the plates 39 provided with suitably spaced open slots 3t) which engage the beams l and it; from above. It to be noted that a number ol. these plates 28) are to be used with the slots Sltl di li'erent'ly spaced.

The beams it and 253 have secured to the depeinlinnstainlards 31 thereof the plows Zlil ot" a conventional type but preferably of a character employed tor the PtllPOStrS ot cultivating.

As is illustrated in Figure 1 two sets or groups of beams -l: and are employed, each group or set being capable of adjustmeat or regulation independently of the other.

lllependingr from the ran. portion ol the lrame and at sulnttantially its transverse center a substantially ll-shaped member on which Forms a e'uideway tor the slid- .lhis hearing has extending: upwardly therelrom a rod 61 which is directed through the loot-inc l9 and has its upper end portion operatively engaged. as at (5:3. with the roc arm (Sc-l carried by the pivoted end portion ol the hand lever til. 'lhia lever til is pivotally con nected. as at lit). with an upstanding raclv llil carried by the lloorinp; il and the lever til; is also provided with a latch mechanism ld' coat-tint: in a well-known manner with said raclc ea. lute posed between the doorinn l9 and the bloilt or llttil'llltl (ill is an expansible member ltd. herein disclosed as a coil spring. surrounding the rod tit and whirh nerves to constantly urge the block or hearing ti l downwardly. lly proper manipulation ol: the lever (at said blorh may be raieed as desired.

The hloclt or hearing); (ill is provided with a central opening- (in in which is arranged a rock bearing "l0 through which is disposed the shaft '71. lhe rear end portion of the shaft Til is provided with a depending; arm T2 carryiin the chopper blade 73. The lorward end portion of the shaft Tl is connected by a universal joint i l with the shaft rotatably supported by the bearing 76 carried by the frame F. The forward end portion of the shaft 75 is in driven connection through the medium of the gears T7 with the transversely disposed shaft 73 rotatably supported by the Ttl'illllt) l1 and extending to one side thereol'i. The extended portion of the shalt T8 is operatively connected by the chain it) with one ol. the supporting wheels \V mounted upon the spindles 80 ot the axle A so that when the implement is in transit requisite rotation will be imparted to the shaft, 71 to etleci the desired chopping action. \Vhen desired the block or bearing: 60 may be raised sutticicntly to render the blade 73 inope alive or it prelerrcd the gears 77 may be disconnected.

l1 roin the lmregroing description it is thought to be obvious that an agricultural implement constructed in accordance with my invention is particularly well adapted for use by reason ot the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and 1nodilication without depart:- inp; 'lrom the principles and spirit thereot and for this reason I do not wish to be understood as limiting mysel't to the precise arrangement; and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

An agricultural implement comprising, in combination, a portable body, a beam pivotally engaged therewith lor movement in a vertical direction. a rigid link carried by the rear portion ol' the beam. a vertically disposed rod freely disposed through said linlt. an arcuate member carried by the body. the upper portion ol the rod overlying said member, a member adapted to be seleclively engaged at lil'l'creut points with the arcuate membe' and strat lclline the rod, a guide member carried by the body through which the. rod is directed, an expansiblc member sin-remitting the rod between the beam and the guide member for constantly urging the beam; downwardly, and ground enn'agii'ig means carried by the beam.

In testimony whereof I hereunto atlix-my signature.

RUBIN L. DIAMOND.
